I've been trying to find answers about fitment but nothing seems clear/definitive.

I'm running stock 400Ms, 18x8 ET34 225/45 on my 2016 F32 xDrive Coupe and I'm getting a good deal on ZITO 19 inch wheels but I'm not sure if they will fit without any issue on stock xDrive suspension, right now I don't have any plans of lowering my car so I just need opinions on stock suspension fitment of these wheels.

Tirerack approves 19x10 ET37 for rear and 19x9 ET32 for the front and the wheels in question have 3mm more offset.

Willtheyfit.com shows rear wheels will be 31.4mm close to suspension struts and poke out 19.4mm, front wheels will be 13.7mm closer to the suspension and poke out 11.7mm.

Apart from fitment what would be ideal tire size making the wheels+tires equal to stock diameter?

And will the handling/performance/speed suffer because of this setup? These are flow-formed so I believe might be equal to the weight of my stock cast wheels even being bigger in size.

Any suggestions will be highly appreciated.

Thank You.
